Are there any routers supported by OpenWrt that can handle 1Gbps WAN to LAN? My current router only pulls 150Mbps and I want to keep OpenWrt due to the amount of custom network configuration that has been done.
Maybe the Turris Omnia if you need WiFi and aren't worried about cost: https://omnia.turris.cz/en/
The NetGear R7800 would be somewhere between the two in cost, and reportedly does GB for wired, somewhat less over WiFi. Pretty easy to find used ones for $100USD too.
